  • Patent number: 11765827
    Abstract: A multilayer printed circuit board is provided having a first dielectric layer and a first plating resist selectively positioned in the first dielectric layer. A second plating resist may be selectively positioned in the first dielectric layer or a second dielectric layer, the second plating resist separate from the first plating resist. A through hole extends through the first dielectric layer, the first plating resist, and the second plating resist. An interior surface of the through hole is plated with a conductive material except along a length between the first plating resist and the second plating resist. This forms a partitioned plated through hole having a first via segment electrically isolated from a second via segment.

  • Patent number: 9900978
    Abstract: Embodiments of the present application relate to the technical field of a printed circuit plate, in particular, to a printed circuit plate and a method manufacturing same so as to resolve a problem of an incomplete elimination of a short-line effect. The method for manufacturing a printed circuit board in the embodiments of the present application comprises a step of drilling target prepregs at positions corresponding to at least one preset hole therein so as to form through holes perforating through the target prepregs, wherein the formed through holes have an aperture greater than that of the preset hole, and the preset hole does not need to transmit electrical signal between layers of the PCB.

  • Patent number: 8667675
    Abstract: Systems and methods for simultaneously partitioning a plurality of via structures into electrically isolated portions by using plating resist within a PCB stackup are disclosed. Such via structures are made by selectively depositing plating resist in one or more locations in a sub-composite structure. A plurality of sub-composite structures with plating resist deposited in varying locations are laminated to form a PCB stackup of a desired PCB design. Through-holes are drilled through the PCB stackup through conductive layers, dielectric layers and through the plating resist. Thus, the PCB panel has multiple through-holes that can then be plated simultaneously by placing the PCB panel into a seed bath, followed by immersion in an electroless copper bath. Such partitioned vias increase wiring density and limit stub formation in via structures. Such partitioned vias allow a plurality of electrical signals to traverse each electrically isolated portion without interference from each other.
